Question

The density of mercury is 13.6gm/cubiccm. Determine the mass of 5L of mercury in kilogram.​

Answer 1

Given:

Density of mercury is 13.6 gm/cm³.

To find:

Mass of 5L of mercury in kg unit.

Calculation:

Density is a scalar quantity having magnitude and represented as the ratio of mass of an object and its volume.

In other words, it represents the mass associated with unit volume of an object.

\therefore \: density = \dfrac{mass}{volume}∴density=

volume

mass

= > mass = density \times volume=>mass=density×volume

= > mass = 13600 \: \dfrac{kg}{ {m}^{3} } \times \dfrac{5}{ {10}^{3} } \: {m}^{3}=>mass=13600

= > mass = 13.6 \times 5=>mass=13.6×5

= > mass = 68 \: kg=>mass=68kg

So , final answer is :

Mass of 5L mercury is 68 kg.
